Description

シガレットのための包材の製造方法Method of manufacturing packaging material for cigarette
　本発明は、シガレットのための包材を製造する方法に関する。 The present invention relates to a method for producing a packaging material for cigarettes.
　近年、低延焼性を有したシガレットが開発されている。このシガレットはたとえ着火されたままの状態で可燃物上に置かれても、可燃物が延焼する可能性を低下させる（例えば、特許文献１）。 In recent years, cigarettes with low fire spread have been developed. Even if this cigarette is placed on a combustible material in an ignited state, the possibility of the combustible material to spread is reduced (for example, Patent Document 1).
　特許文献１のシガレットは紙製の包材を含み、この包材は燃焼抑制剤からなる複数のバンド層を有する。これらバンド層はシガレットの全周を囲み且つシガレットの軸線方向に所定の間隔を存して配置されている。 The cigarette of Patent Document 1 includes a paper packaging material, and this packaging material has a plurality of band layers made of a combustion inhibitor. These band layers surround the entire circumference of the cigarette and are arranged at a predetermined interval in the axial direction of the cigarette.
　より詳しくは、上述した包材を製造する方法は、包材となるウエブを走行させながら、ウエブに液状の燃焼抑制剤を間欠的に塗布することにより、ウエブにバンド層を形成し、この後、ウエブとともにバンド層を乾燥させる。 More specifically, in the method of manufacturing the packaging material described above, a band layer is formed on the web by intermittently applying a liquid combustion inhibitor to the web while running the web serving as the packaging material. The band layer is dried together with the web.
　特許文献１に開示された製造方法は、バンド層を形成するにあたり、ウエブへの燃焼抑制剤の塗布処理を複数回に分けて実施し、そして、各塗布処理の直後にウエブの乾燥処理をそれぞれ実施する。 In the production method disclosed in Patent Document 1, the formation of the band layer is performed by applying the application of the combustion inhibitor to the web in a plurality of times, and the web drying process is performed immediately after each application process. carry out.
　特許文献１の製造方法によれば、燃焼抑制剤の塗布処理及び乾燥処理が複数回に分けて実施されるので、各塗布処理のために要求される燃焼抑制剤の塗布量は少なくて済む。それ故、各塗布処理後、燃焼抑制剤が塗布されたウエブの塗布領域が乾燥処理により収縮するとしても、塗布領域以外のウエブの未処理領域に生じる皺は最少限に抑制され、ウエブ、即ち、包材品質を維持できるものと考えられる。 According to the manufacturing method of Patent Document 1, since the application process and the drying process of the combustion inhibitor are performed in a plurality of times, the amount of application of the combustion inhibitor required for each application process is small. Therefore, even after the application process, even if the application area of the web to which the combustion inhibitor is applied shrinks due to the drying process, wrinkles generated in the unprocessed area of the web other than the application area are suppressed to the minimum, that is, the web, It is considered that the packaging quality can be maintained.

特表2004-512849号公報Special Publication 2004-512849
　しかしながら、特許文献１の製造方法の場合、塗布処理毎に燃焼抑制剤の塗布装置が必要になるばかりでなく、乾燥処理のための乾燥装置もまた塗布処理毎に要求される。それ故、特許文献１の製造方法を実施する製造設備自体のみならず、製造設備の保守点検に多大な費用が掛かり、低延焼性シガレットのための安価な巻紙を提供することができない。 However, in the case of the manufacturing method of Patent Document 1, not only a combustion inhibitor coating device is required for each coating process, but also a drying device for the drying process is required for each coating process. Therefore, not only the manufacturing equipment itself that implements the manufacturing method disclosed in Patent Document 1, but also the maintenance and inspection of the manufacturing equipment is very expensive, and it is not possible to provide an inexpensive wrapping paper for the low fire spread cigarette.
　本発明の目的は、品質に優れたシガレットのための包材を安定し且つ安価に製造することができる方法を提供することにある。 An object of the present invention is to provide a method capable of stably and inexpensively producing a packaging material for cigarettes having excellent quality.
　上記の目的を達成するため、本発明の製造方法は、シガレットのための包材を形成するウエブを走行させる工程と、ウエブの走行過程にて、ウエブの一方の面に液状の燃焼抑制剤を塗布し、この燃焼抑制剤のバンド層を形成するための工程であって、バンド層はウエブの幅方向に全幅に亘って延び、且つ、ウエブの走行方向に所定の間隔を存して配置される、工程と、ウエブの走行過程にて、燃焼抑制剤が塗布される前又は後に、前記ウエブに水を塗布する工程と、燃焼抑制剤及び水が塗布されたウエブを乾燥する工程と
を備える。 In order to achieve the above object, the manufacturing method of the present invention includes a step of running a web for forming a packaging material for cigarette, and a liquid combustion inhibitor on one surface of the web in the course of running the web. It is a step for applying and forming a band layer of this combustion inhibitor, the band layer extending over the entire width in the width direction of the web, and being disposed at a predetermined interval in the running direction of the web. A step of applying water to the web before or after the combustion inhibitor is applied in the course of running the web, and a step of drying the web to which the combustion inhibitor and water have been applied. .
　上述の製造方法によれば、ウエブが乾燥処理を受ける前、ウエブには水が塗布されているので、この後、ウエブが乾燥されても、ウエブ全体の収縮を一様にすることができ、皺の無いウエブ、即ち、ハンド層を有し且つ皺の無いシガレットのための包材が製造される。 According to the above manufacturing method, before the web is subjected to a drying treatment, water is applied to the web, so that even after the web is dried, the shrinkage of the entire web can be made uniform. Wraps are produced for wrinkle-free webs, ie cigarettes with a hand layer and without wrinkles.
　具体的には、水を塗布する工程は、燃焼抑制剤が塗布される前に実施され、そして、水はウエブの一方の面にその全域に亘って塗布される。 Specifically, the step of applying water is performed before the combustion inhibitor is applied, and the water is applied to one side of the web over the entire area.
　この場合、液状の燃焼抑制剤は、水に比べて高い粘性を有しているのが望ましく、具体的には、液状の燃焼抑制剤は、アルギン酸ナトリウムの水溶液である。 In this case, it is desirable that the liquid combustion inhibitor has a higher viscosity than water. Specifically, the liquid combustion inhibitor is an aqueous solution of sodium alginate.
　一方、水を塗布する工程は、燃焼抑制剤が塗布された後に実施されてもよく、この場合、水はウエブの他方の面にその全域に亘って塗布される。 On the other hand, the step of applying water may be performed after the combustion inhibitor is applied. In this case, the water is applied to the other surface of the web over the entire area.
　更に、水は、ウエブの一方の面にて、燃焼抑制剤が塗布された領域以外のウエブの領域のみに塗布されてよい。この場合、液状の燃焼抑制剤は、スクリーンローラを使用して前記ウエブに塗布され、水は、グラビアローラを使用してウエブに塗布される。 Furthermore, water may be applied to only one area of the web except for the area where the combustion inhibitor is applied. In this case, the liquid combustion inhibitor is applied to the web using a screen roller, and the water is applied to the web using a gravure roller.
　本発明の包材の製造方法は、ウエブの乾燥処理を実施する前に、ウエブに水を塗布する。それ故、ウエブへの液状の燃焼抑制剤の塗布に拘わらず、ウエブが乾燥処理されても、燃焼抑制剤のバンド層を有し且つ皺の無い包材の製造が可能となる。 In the method for manufacturing a packaging material of the present invention, water is applied to the web before the web is dried. Therefore, regardless of the application of the liquid combustion inhibitor to the web, even when the web is dried, it is possible to produce a packaging material having a band layer of the combustion inhibitor and having no wrinkles.
　ウエブに対する燃焼抑制剤の塗布処理や乾燥処理はそれぞれ１回で済むので、製造方法を実施する設備は大幅に簡略化され、安価な包材の提供が可能となる。 Since the application of the combustion inhibitor to the web and the drying treatment are each performed once, the equipment for carrying out the manufacturing method is greatly simplified, and it is possible to provide an inexpensive packaging material.

発明を実施するための形態BEST MODE FOR CARRYING OUT THE INVENTION
　図１は低延焼性のフィルタシガレットを示す。このフィルタシガレットは、シガレット２と、このシガレット２の一端に隣接して配置されたフィルタ６とを含み、これらフィルタ６及びシガレット２はチップペーパ４の巻付けにより互いに接続されている。シガレット２は、刻たばこＴと、この刻みたばこＴを棒形状に包み込む包材８とを有する。包材８には複数のバンド層１０が形成され、これらバンド層１０はシガレット２に低延焼性を提供する。より詳しくは、バンド層１０は一定の幅Ｈを有し、シガレット２の全周に亘って延び、更に、シガレット２の軸線方向に所定のピッチＰを存して配置されている。例えば、バンド層１０の幅Ｈ及びピッチＰはそれぞれ、７ｍｍ、２７ｍｍである。 Fig. 1 shows a low-fired filter cigarette. The filter cigarette includes a cigarette 2 and a filter 6 disposed adjacent to one end of the cigarette 2, and the filter 6 and the cigarette 2 are connected to each other by winding a chip paper 4. The cigarette 2 has the tobacco T and the packaging material 8 which wraps the tobacco T in a rod shape. A plurality of band layers 10 are formed on the packaging material 8, and these band layers 10 provide the cigarette 2 with low fire spread. More specifically, the band layer 10 has a constant width H, extends over the entire circumference of the cigarette 2, and is further disposed with a predetermined pitch P in the axial direction of the cigarette 2. For example, the width H and the pitch P of the band layer 10 are 7 mm and 27 mm, respectively.
　包材８は、図２に示されるウエブＷを所定の長さ毎に切断して得られ、ウエブＷには、上述した幅Ｈ及びピッチＰのパターンにて、バンド層１０が形成されている。バンド層１０は液状の燃焼抑制剤、具体的にはアルギン酸ナトリウムの水溶液をウエブＷに塗布し、この後、ウエブＷを乾燥させることで得られる。なお、水溶液は、アルギン酸ナトリウムを２～４重量％含む。 The packaging material 8 is obtained by cutting the web W shown in FIG. 2 into predetermined lengths, and the band layer 10 is formed on the web W with the pattern of the width H and the pitch P described above. . The band layer 10 is obtained by applying a liquid combustion inhibitor, specifically, an aqueous solution of sodium alginate to the web W, and then drying the web W. The aqueous solution contains 2 to 4% by weight of sodium alginate.
　バンド層１０が形成されたウエブＷはシガレット製造機に供給され、このシガレット製造機はウエブＷを使用して、バンド層１０を有するシガレット２を製造する。 The web W on which the band layer 10 is formed is supplied to a cigarette manufacturing machine, and the cigarette manufacturing machine uses the web W to manufacture the cigarette 2 having the band layer 10.
　図３は、上述したウエブＷを製造するための製造設備を概略的に示し、この製造設備は第１実施例の製造方法を実施する。 FIG. 3 schematically shows manufacturing equipment for manufacturing the above-described web W, and this manufacturing equipment implements the manufacturing method of the first embodiment.
　製造設備はウエブＷの繰出しリールＲ１を備え、この繰出しリールＲ１は巻取りリールＲ2に向けてウエブＷを繰出し経路に沿って繰出し、この後、繰出されたウエブＷは巻取りリールＲ2に巻取られる。 The production facility includes a feeding reel R1 for the web W. The feeding reel R1 feeds the web W along the feeding path toward the take-up reel R2, and then the fed web W is taken up on the take-up reel R2. It is done.
　繰出し経路には塗布装置１２が配置されている。この塗布装置１２は、グラビアローラ１４及びピンチローラ１６を含み、繰出し経路はグラビアローラ１４とピンチローラ１６との間を通過し、それ故、これらグラビアローラ１４及びピンチローラ１６はウエブＷを挟み込むことができる。ウエブＷが繰出し経路に沿い、リールＲ1からリールＲ2に向けて走行され、そして、塗布装置１２を通過するとき、グラビアローラ１４はウエブＷの片面、即ち、その裏面にアルギン酸ナトリウムの水溶液を間欠的に塗布し、前述のパターンのバンド層１０ａを形成し、これらバンド層１０ａは乾燥前の状態にある。 The coating device 12 is arranged in the feeding path. The coating device 12 includes a gravure roller 14 and a pinch roller 16, and the feeding path passes between the gravure roller 14 and the pinch roller 16, so that the gravure roller 14 and the pinch roller 16 sandwich the web W. Can do. When the web W travels from the reel R1 to the reel R2 along the feeding path and passes through the coating device 12, the gravure roller 14 intermittently applies an aqueous solution of sodium alginate on one side of the web W, that is, the back side thereof. To form a band layer 10a having the above-mentioned pattern, and these band layers 10a are in a state before drying.
　本実施例の場合、繰出し経路には、塗布装置１２の上流に水の塗布装置１８が更に配置されている。この塗布装置１８は、水槽２０と、この水槽２０内に部分的に浸けられた塗布ローラ２２と、この塗布ローラ２２の直上に配置されたピンチローラ２４とを含み、ウエブＷは塗布ローラ２２とピンチローラ２４との間を通過する。ウエブＷが塗布装置１８を通過する際、塗布ローラ２２はウエブＷの裏面の全域に水を塗布する。 In the case of the present embodiment, a water applicator 18 is further arranged upstream of the applicator 12 in the feeding path. The coating device 18 includes a water tank 20, a coating roller 22 partially immersed in the water tank 20, and a pinch roller 24 disposed immediately above the coating roller 22. It passes between the pinch rollers 24. When the web W passes through the coating device 18, the coating roller 22 applies water to the entire back surface of the web W.
　更に、繰出し経路には塗布装置１２の下流に乾燥装置２６が配置されている。繰出し経路は乾燥装置２６内を通過している。ウエブＷが乾燥装置２６内通過するとき、乾燥装置２６はバンド層１０ａとともにウエブＷを急速に乾燥させてバンド層１０を形成し、バンド層１０を有するウエブＷを巻取りリールＲ2に向けて送出する。 Furthermore, a drying device 26 is disposed downstream of the coating device 12 in the feeding path. The feeding path passes through the drying device 26. When the web W passes through the drying device 26, the drying device 26 rapidly dries the web W together with the band layer 10a to form the band layer 10, and sends the web W having the band layer 10 toward the take-up reel R2. To do.
　上述の製造設備を使用する第１実施例の製造方法によれば、ウエブＷが繰出しリールＲ1から巻取りリールＲ2に向けて走行する過程にて、先ず、ウエブＷの裏面全体に塗布装置１８により水が塗布される。この後、ウエブＷの裏面に塗布装置１２によりバンド層１０ａを形成するアルギン酸ナトリウムの水溶液が塗布される。この水溶液は水に比べて粘性が高い。このため、ウエブＷに塗布された水溶液は、ウエブＷに既に塗布された水を押し退け、前述したパターンのバンド層１０ａを正確に形成する。 According to the manufacturing method of the first embodiment using the above-described manufacturing equipment, first, in the process in which the web W travels from the supply reel R1 toward the take-up reel R2, first, the entire back surface of the web W is applied by the coating device 18. Water is applied. Thereafter, an aqueous solution of sodium alginate for forming the band layer 10 a is applied to the back surface of the web W by the coating device 12. This aqueous solution is more viscous than water. For this reason, the aqueous solution applied to the web W pushes away the water already applied to the web W to accurately form the band layer 10a having the pattern described above.
　この後、ウエブＷが乾燥装置２６内に進入したとき、ウエブＷは例えば１００℃～２００℃、好ましくは１７０℃の乾燥温度まで加熱され、この乾燥温度にて急速に乾燥される。ウエブＷの裏面にはその全体に水が塗布されているので、ウエブＷが急速に乾燥されても、ウエブＷはその全体が一様に収縮する。それ故、バンド層１０ａ以外の領域、即ち、アルギン酸ナトリウムの水溶液が塗布されていない領域に皺が発生することはない。この結果、バンド層１０を有していても、皺の無いウエブＷ、即ち、包材８が製造される。 Thereafter, when the web W enters the drying device 26, the web W is heated to a drying temperature of, for example, 100 ° C. to 200 ° C., preferably 170 ° C., and is rapidly dried at this drying temperature. Since water is applied to the entire back surface of the web W, even when the web W is rapidly dried, the entire web W contracts uniformly. Therefore, wrinkles do not occur in the region other than the band layer 10a, that is, the region where the aqueous solution of sodium alginate is not applied. As a result, even if it has the band layer 10, the web W without wrinkles, ie, the packaging material 8, is manufactured.
　また、第１実施例の製造方法によれば、バンド層１０ａを形成する塗布処理やウエブＷの乾燥処理はそれぞれ１回ずつで済むことから、製造設備の構造が大形化したり、複雑化したりすることはなく、包材８は安価にして提供される。 In addition, according to the manufacturing method of the first embodiment, the coating process for forming the band layer 10a and the drying process for the web W only need to be performed once, so that the structure of the manufacturing facility becomes large or complicated. The packaging material 8 is provided at a low cost.
　なお、第１実施例の場合、バンド層１０はウエブＷの表面に形成されてもよい。 In the case of the first embodiment, the band layer 10 may be formed on the surface of the web W.
　図４は、第２実施例の製造方法を実施する製造設備を概略的に示す。
　図４の製造設備は、図３の製造設備とは以下の点のみで相違する。即ち、図４の製造設備は、前述したアルギン酸ナトリウムの水溶液を塗布する塗布装置１２が水を塗布する塗布装置１８の上流に配置されている。 FIG. 4 schematically shows a production facility for carrying out the production method of the second embodiment.
The manufacturing facility of FIG. 4 differs from the manufacturing facility of FIG. 3 only in the following points. That is, in the manufacturing facility of FIG. 4, the coating device 12 that applies the aqueous solution of sodium alginate described above is disposed upstream of the coating device 18 that applies water.
　それ故、図４の製造設備を使用する第２実施例の製造方法によれば、先ず、ウエブＷの表面にバンド層１０ａが形成され、この後、ウエブＷの裏面全域に水が塗布され、そして、ウエブＷは乾燥処理を受ける。このような場合にも、バンド層１０を有し且つ皺の無いウエブＷが同様にして製造される。 Therefore, according to the manufacturing method of the second embodiment using the manufacturing facility of FIG. 4, first, the band layer 10a is formed on the surface of the web W, and then water is applied to the entire back surface of the web W, Then, the web W is subjected to a drying process. Even in such a case, the web W having the band layer 10 and having no wrinkles is manufactured in the same manner.
　図５は、第３実施例の製造方法を実施する製造設備を概略的に示す。
　図５の製造設備は、図３の塗布装置１２，１８に置換された塗布装置２８，３０をそれぞれ備えている。塗布装置２８は、塗布装置１２のグラビアローラ１４の代わりにスクリーンローラ３２を使用し、このスクリーンローラ３２はグラビアローラ１４と同様にウエブＷの裏面にバンド層１０ａを形成する。 FIG. 5 schematically shows a production facility for carrying out the production method of the third embodiment.
The manufacturing equipment in FIG. 5 includes coating devices 28 and 30 that are replaced with the coating devices 12 and 18 in FIG. The coating device 28 uses a screen roller 32 instead of the gravure roller 14 of the coating device 12, and the screen roller 32 forms a band layer 10 a on the back surface of the web W in the same manner as the gravure roller 14.
　一方、塗布装置３０は、塗布装置１８の塗布ローラ２２の代わりにグラビアローラ３４を使用し、このグラビアローラ３４は、ウエブＷの裏面の一部に水を塗布する。より詳しくは、グラビアローラ３４は、ウエブＷに下流側の塗布装置２８によってバンド層１０ａが形成されるべきバンド形成領域以外のバンド無し領域のみに水を塗布する。 On the other hand, the coating device 30 uses a gravure roller 34 instead of the coating roller 22 of the coating device 18, and this gravure roller 34 applies water to a part of the back surface of the web W. More specifically, the gravure roller 34 applies water to the web W only in the band-free region other than the band forming region where the band layer 10a is to be formed by the coating device 28 on the downstream side.
　図５の製造設備は、塗布装置２８，３０間に配置されたセンサ３６を更に備えている。このセンサ３６は、ウエブＷに塗布された水、即ち、ウエブＷのバンド無し領域（図２中の参照符号Ａ）を検出し、その検出信号を制御装置３８に供給する。この制御装置３８はセンサ３６からの検出信号に基づき、スクリーンローラ３２の回転を制御し、これにより、スクリーンローラ３２はウエブＷのバンド無し領域間、即ち、バンド形成領域にバンド層１０ａを正確に形成することができる。 5 further includes a sensor 36 disposed between the coating devices 28 and 30. The sensor 36 detects water applied to the web W, that is, a band-free region (reference numeral A in FIG. 2) of the web W, and supplies a detection signal to the control device 38. The control device 38 controls the rotation of the screen roller 32 based on the detection signal from the sensor 36, whereby the screen roller 32 accurately places the band layer 10a between the band-less regions of the web W, that is, in the band forming region. Can be formed.
　上述した図５の製造整備を使用する第３実施例の製造方法によれば、先ず、ウエブＷの裏面のうち、バンド無し領域のみに水が塗布され、この後、バンド無し領域間にバンド層１０ａが形成される。この後、ウエブＷは乾燥装置２６に供給され、この乾燥装置２６により乾燥され、バンド層１０を有し且つ皺の無いウエブＷが製造される。 According to the manufacturing method of the third embodiment using the manufacturing maintenance of FIG. 5 described above, first, water is applied only to the bandless area on the back surface of the web W, and thereafter, the band layer is formed between the bandless areas. 10a is formed. Thereafter, the web W is supplied to the drying device 26, and is dried by the drying device 26, whereby the web W having the band layer 10 and having no wrinkles is manufactured.
　なお、第３実施例の製造方法の場合、塗布装置２８，３０の位置は入れ替え可能である。
　更に、本発明は上述の実施例にも制約されない。 In the case of the manufacturing method of the third embodiment, the positions of the coating devices 28 and 30 can be interchanged.
Furthermore, the present invention is not limited to the above-described embodiments.
　例えば、本発明の製造方法は、繰出しリールＲ1から巻上機に向けてウエブＷが供給される過程にて、ウエブＷに対する水の塗布及びバンド層１０ａの形成を実施することができる。また、バンド層の形成にはアルギン酸ナトリウムの水溶液以外の液状の燃焼抑制剤をも使用可能である。 For example, in the manufacturing method of the present invention, water can be applied to the web W and the band layer 10a can be formed in the process in which the web W is supplied from the supply reel R1 to the hoisting machine. In addition, a liquid combustion inhibitor other than an aqueous solution of sodium alginate can be used for forming the band layer.
